Tm Fort MANURE-CARRIERS. I

To all whom it may concern Be it known that I, ALBERT SNESRUD, a citizen of the United States, residingat Webster, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Trips for Manure-Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

My invention has for its object to provide an extremely simple and efficient tripping device for manure carriers or like apparatus which includes a trolley arranged to run on a wire or cable and having a dumping bucket.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawingsi Figure 1 is a view in side elevation and,

some parts broken away, showing the tripping device applied to an elevated track cable and showing also the tripping plunger of the trolley; and

Fig. 2 isa section on the line 22 of Fig. 1. i

The numeral 3'indicates an elevated track cable which may be a heavy wire, a rod,

or woven wire cable and may be supported in the usual way.

The tripping device comprises a trip housing formed from sheet metal, loent into U- shaped form, as indicated by numeral 4.

p This housing straddles the cable 3 and hangs thereon like a saddle and, of course, is slidably adjustable thereon.

The numeral 5 indicates a frictional clamping dog that is pivoted at one end on a nut-equipped bolt 6 passed through the sides of the housing. This dog 6 is in the form of a quite stifl fiat spring, the extended arm of which has a depressed bulge 7. The numeral 8 indicates a clamping lever pivoted on a nut-equipped bolt 9 passed through the housing 4; and provided at its pivoted end with a cam lug 10 that is engageable with the depressed portion 7 of the dog 6. The numeral 11 indicates a tripping lever pivotally hung at one end on the nutequipped bolt 12 passed through the housing 1. The tripping lever 11 is bent on the line of a compound curve, so that it will engage the clamping 1ever8, as indicated by Specification of Letters Patent.

depression of the trip ing plunger 13. Normally, the tripping plunger 13 will stand at the elevation indicated by dotted lines in Fig. 1.

The tripping device will be set on a cable atany desired point and from time to time will be shifted so as to trip the bucket at the proper place.

When the tripping device is to be moved, the clamping lever 8 will be turned down thereby releasing the frictional clamping dog 5 from the cable and permitting the housing 4 then to be slid freely on the cable.

To secure the housing into fixed position on the cable, the clamping lever 8 is forced back upward to the position indicated in Fig. 1, thereby causing the cam lug 10 thereof to press against the bulge 7 of said dog, and this will press the dog 5 upward and cause the same to engage the under side of the cable at two points, to wit, at points near the extremities of its bulged portion 7 The frictional clamping action thus produced on I Patented Oct. 19, 1920. 1 Application filed Maya, 1920. Serial No. 378,137.

the cableby the top of the housing 4=- and by the spring dog 6 will be suflicient to prevent sliding of the housing 4 on the cable under the tripping act.

The tripping action produced is'as follows:

When the bucket equipped trolley, with its load, is moved outward or toward the right in respect to Fig. 1, its plunger 13, when it reaches the position marked a on Fig. 1,

said tripping lever cannot be moved farther upward than said broken line position, because it is stopped by the clamping lever 8 and the clamping lever 8 is stopped against further upward movement by the engagement of its free end with the cable 3.

When the trolley with its loaded bucket tripping the tripping full lines in Fig. 1, thereby tripping the' is then moved farther toward the right, the lever 11 will cam downor depress bucket and permitting the same to drop its load. The trolley with its dump bucket will still move onward to/ the right until its depressed tripping plunger 13 has moved be-.

yond 'thetripping lever'll and has auto matically then moved normal position;

WVhen the trolley and bucket are given again upward to its their return movement toward the left, the

tripping plunger 13 will engage the depending tripping lever 11 after it reaches the condition I) in Fig. 1, and will cause'rthe said lever to freely swing to the position indicated in dotted lines in Fig. 1; and when the said plunger 13 reaches its position 0 Fig. 1, it' will pass from under'the said lever 11' and permit the latter toagain swing back to its depending position. 1

The tripping device above described is of small cost, hence may bequickly and easily operated and. adjusted, and in practice has been found highly efiicient for the purposes had in view.

\Vhat I claim is:

an operative position, said tripping lever beingfree to swing in opposite direction, to an inoperative position;

plunger 13, as indicated by- 2. Thecombination with a cable, or a tri ping device; comprising a U shaped casing, embracing and mounted to slide thereon, a

spring-acting" clamping dog applied within" said casing and engageable with the under 'si dof the cable, a clamping lever pivoted to said casing and having a lug working With'a cam action against said dog, and a tripping lever pivoted to sald casing, normally depending therefrom and arranged to, bevengaged with said clamping lever and thereby-stopped in an operative position,

said tripping lever being free to swing in oppositedirection, to an inoperative p'osi- 7 "tion, theff'ree end of. said clamping lever being engageable with theunder side of said cable to limit its movement Vinthe direction.

in which it is pressed by an engagement therewith of said tripping lever.

3. The combination with a cable,.of a.

tripping device comprising a I U shaped housing arranged to embrace and to slide upon said cable, a clampingdog pivotally connected to said housing at one end and having downwardly curved depressed portions, the extremities of which are engageable with, the under side of said cable, a clamping lever pivoted to said housing and provided with a cam lug operative on the curvedportion of said dog to press the same into engagement ofsaid cable, the 'free endof saidclampinglever being arranged to engage the under side of said cable to portion, and/a longitudinally curvedtripping lever pivoted to said housing at one end and normally depending therefrom but' engageable with said clamping lever to limit its movement in one direction to. an operative trip-actuating'position.
